I'm having trouble adding padding to the right and left sides of the card in Bootstrap 4. Here is the code snippet:

<section class="question-section">
<div class="container">
<div class="row padding-xs">
<div class="card shadow-lg rounded-lg" style="width: 30rem;">
<div class="pt-3">
<img class="card-img-top" src="question.svg" alt="Card image cap" height="128px" width="128px">
</div>
<div class="card-body">
<h5 class="card-title text-center">How will you utilize the device?</h5>
<p class="card-text text-center">All-day workhorse or gaming machine?
Or just casual internet browsing?</p>
</div>
<div class="input-group pr-3 pl-3 pt-3 pb-5">
<select class="custom-select" id="inputGroupSelect04">
<option selected>Select...</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<div class="input-group-append">
<button class="btn btn-outline-dark text-dark" type="button">Confirm</button>
